YIACHINE FOR MAKING FUSES.

Specification of Letters Patent No. 8,963, dated May 25, 1852.

To all whom it 'may concern:

Be-it known that I, ALBERT F. ANDREWS, of Avon, in the county of Hartford and State of Connecticut, have invented a new 'and useful Improvementin Manufacturing Fuses vfor Blasting, &c.; .and I do hereby declare that the following is a full,el ear,

'and exact description of the construction and operation of the same, reference being had tothe accompanying drawings, which make a part of this specification, in which- A, is the spool stand, and spools which contam the varinfor materlal of Whlch the body of the fuse is made.

Bl, is the hopper in which the poifvder is v placed.

'contain 'the winding thread Ywound to draw C, .is the fuse as twisted a, the threads .vhifh Wind the fuse:*D, the spools which :-E, the flyers which directt-he thread F, the hollow tube through which the fuse passes to be Wound "G, the fuse as finished, and readyfor tarring:-II, the shaft` on which the fuse is it through with the proper velocity tosuitthetwisting, &c`.

I make the frame of posts and ybars of any'suitable material, and in any suitable way, as seen in the drawings, and ofa con- `venientsize, say' four to feet long, &c. I make a rex-'olving spool stand A, capable ot' lnrldingthe requisite number of spools,

(say eight,). with a. hollow shaft passing. ldown through its eente1,

sustained in two (as seen at b, and (a) on which the spool stand is revolved, horizontally, by means of pullcy,`e. the flyers, E, with a hollow arbor, or shaft, I'place a suitable spools of winding The ends of these suitable. bearings,

thread, as seeuat D.

' -winding threadspass through suitable holes,

(or otherwise,) inthe bar of the flyers, and are again carried` 'and are down, from near the end, .passed through holes, properly graduated, in the hollow shaft, F, (as seen at a,) and Wind around the twisted fus as it vpasses through the hollow shaft, and

thus finishes the fuse ready for tarring.

The yarns from the spools, (on the spool stand, A,) are passed down'through the draw the fuse, (C, (l.) ioiivard I make.

(around an antiffriction rol-ler, if deemed necessary,) (Where, by revolving lthe spool stand, A, the fuse is twisted,) and through the horizontal hollow shaft, F, of the flyers, E, (where the fuse is Wound, and then to the arbor, (or spooh) Il, which receives the `fuse-vhen finished ready for tarring.

Having constructed l the several parts,4 and arranged them in their proper positions, as before described', and A in the hopper, IS, the lower end .of the tube of which communicates with the upper opening of the hollow shaft of the spool stand, with all the yarns around it.) I put the machine in operation -by applying the powento the arbor, or shaft, g, by' means of a crank,- fr, or by any other-suitable means.

'()n the arbor, g, is the bevel gear Wheel, a', which works the bevel gear wheel, 7e, above whichI is a pulley, Z, which by means band, m, and the pulley, e, the spool stand, A, is revolved, so as to twist the fuse. -Th pulley, I, Aby means of the band, p, and pulley, 1], revolves the hollow arbor, F, and the flyers, E so as .to wind 'hc fuse; while the bevel gear Wheel; n, (on thesiurf, arbor with Z3) Works the bevel gear Wheel, 0,

which by means of lhe pulley, r, thehand, s, and pulley, Fl, the shaft', Il, is made to as fast, as 1tV is t.\viste d,and wound, so as to make the fuse even in itstuist, winding, and supply of powder.

What I'claim as my invention. and desire to secure by Letters latent, is-- Passingv the hollow mandrel through the winding spools, in combination with 'the flyers, E, which direct the winding thread from the dierent spools to the interior of said mandrel for the purpose of Winding the fuse as it passes from the forming machine, When combined, substantially, as herein described.
